Two things:

What is the Secret XFire Hand signal?

I've seen about 2 Xfires, since I leased mine 2 months ago. Rarity Factor still exists in Ann Arbor and Lansing, MI. Funny thing is as BobaFettm was saying in Troy, MI theres quite a few. The two I saw were at Somerset collection, as I pulled into Valet. Though I haven't seen another one yet.
